Note NDIS 5. x has been deprecated and is superseded by NDIS 6. x. For new NDIS driver development, see Network Drivers Starting with Windows Vista. For information about porting NDIS 5. x drivers to NDIS 6. x, see Porting NDIS 5.x Drivers to NDIS 6.0.

FDDI_IS_BROADCAST sets a caller-supplied variable to a Boolean value indicating whether a given FDDI address is a broadcast address.

Syntax

VOID FDDI_IS_BROADCAST(
  _In_  PUCHAR   Address,
  _In_  ULONG    AddressLength,
  _Out_ PBOOLEAN Result
);

Parameters

Address [in]
Pointer to a network address.
AddressLength [in]
Specifies the size in bytes of the address (either 2 or 6).
Result [out]
Pointer to a caller-supplied variable in which this macro returns TRUE if the given address is broadcast.

Return value

None

Remarks

A caller can use the FDDI_LENGTH_OF_SHORT_ADDRESS and FDDI_LENGTH_OF_LONG_ADDRESS constants, corresponding to two and six bytes, respectively, as the value for AddressLength. Note that FDDI_LENGTH_OF_SHORT_ADDRESS is an invalid value for AddressLength in Windows XP and later operating systems.

A broadcast address applies to all stations in the extended network.

Callers of this macro can be running at any IRQL as long as the source address and supplied variable are resident.

Note This macro is not available for use beginning with Windows Vista.

Requirements

Target platform	Desktop
Version	Not supported for NDIS 6.0 drivers in Windows Vista. Supported for NDIS 5.1 drivers in Windows XP.
Header	Ndis.h (include Ndis.h)
IRQL	Any level (see Remarks section)
